Overview: As businesses continue to move critical
operations online, distributed denial of service
(DDoS) attacks are increasing in frequency,
sophistication and range of targets. In a 2011
Verisign study, 63 percent of respondents
reported experiencing at least one attack that
year, while 51 percent reported revenue loss
as a result of downtime from the attack. Those
numbers are undoubtedly higher today as
the size, frequency and complexity of DDoS
attacks continue to grow.

Mitigation against these types of attacks is
challenging and generally requires layered
solutions across data centers and the cloud
in order to manage. The success of these
attacks and their ability to damage a company's
infrastructure, revenue and reputation is
indicative that many IT managers still haven't
found the right protection formula to proactively
mitigate them.
